Wrought Iron vs. Cast Aluminum Patio Furniture: Which Is Better?
Wrought iron is heavier and stronger, so it stays put in wind and has a classic look, but it can rust and needs regular upkeep. Cast aluminum is lighter, can't rust, comes in more styles and colors, and costs less to buy and maintain. For most patios, especially near the coast or a pool, cast aluminum is the better choice. Wrought iron is the pick for windy spots and timeless, heavyweight pieces.

Manufacturing and Durability
The way each material is made is the core difference between them. Wrought iron is heated and then bent, rolled or hammered into shape, often by hand. Cast aluminum is melted in a furnace and poured into a mold.
Wrought iron is the stronger, heavier metal. But strength isn't the same as weather resistance: iron can rust anywhere its finish chips, while aluminum can't rust at all. Outdoors, well-made powder-coated cast aluminum often lasts as long or longer with far less care.
Winner: Wrought iron for raw strength; cast aluminum for weather resistance.
Design and Appearance
Because wrought iron involves more manual work, it comes in fewer shapes, and it leans toward classic and traditional styles. Cast aluminum can be molded into intricate or clean, modern shapes, and powder coating makes it available in a wide range of colors. It fits traditional and modern patios alike.
Winner: Cast aluminum.
Weight
Wrought iron pieces weigh much more than comparable cast aluminum pieces, often 15 to 30 pounds more. That weight is an advantage in windy spots, where lighter furniture can tip or slide. If you like to rearrange your patio, move chairs for outdoor dinners, or store furniture for winter, cast aluminum is much easier to handle.
Winner: Wrought iron for windy spots; cast aluminum for everyone else.
Maintenance
Cast aluminum needs very little care: an occasional wash with mild soap and water keeps it looking new, and it won't rust even after years of rain.
Wrought iron needs more attention. Wipe it regularly with mild dish soap and water, apply a coat of wax once or twice a year to protect the finish, and sand and repaint chips with matching paint as soon as you see them. With that care, wrought iron keeps its strength and good looks for decades.
Winner: Cast aluminum.
Price
Wrought iron is usually more expensive than cast aluminum, partly because it takes more labor to make. It also costs more to maintain over time. Both materials can last for decades. For more on what drives cost, see why patio furniture is so expensive.
